Title: Digital signal transmitter synchronization system
Inventor: WEISS S MERRILL
IPC: H04N21/242
Filed: 2002-03-29
Granted: 2007-03-13
Abstract: Methods for synchronizing a plurality of RF transmitters (20) that are supplied with a common digital information signal for carrier modulation and subsequent transmission a common channel throughout a prescribed region, whereby digital signal receivers within the region receive transmissions on the channel from more than one transmitter (20). The method involves inserting reference signals into the data sent to transmitters in order to place them into known states at specific times relative to the digital signals sent to them for transmission. The digital signals transmitted by each transmitters will be identical to one another so that the receivers are identical to one another so that the receivers can identify one received signal as a main signal and the others as echoes. The signal transmitted by at least one of synchronized transmitters is delayed, such that identical digital signals received from at least two of the transmitters by receivers in the region arrive at each receiver within a prescribed time window.

Abstract: Objective measurement methods and devices for predicting perceptual quality of speech signals degraded in speech rocessing/transporting systems may have poor prediction results for degraded signals including extremely weak or silent portions. Improvement is achieved by applying a first scaling step in a pre-processing stage with a first scalins factor (S(Y+.DELTA.), which is a function of the reciprocal value of the power of the output signal increased by an adjustment value (.DELTA.), and by a second scaling step with a second scaling factor (S.alpha.(Y+.DELTA.); S.alpha.i(Y+.DELTA.i), with i=1, 2), which is substantially equal to the first scaling factor raised to an exponent having a adjustment value (.alpha.) between zero and one. The second scaling step may be carried out on various locations in the device. The adjustment values are adjusted using test signals with well defined subjective quality scores.
